Solved

Split column where ",*"

hello, does anyone know how I could split column where I have string ",t" (that is a comma and no space before next character).

 

Here the "t" is an example, the letters vary.

 

Example:

 

"sports includes football, tennis,badminton"

 

I would like new column for "badminton". The delimiter is comma and no space before the "b". The sports vary but the constant is comma and no space. I hoped I could use a wildcard delimiter like ",*" but this does not work.

 

Is this possible?

 

Many thanks,

    Hi adavid999 

    Place the following M code in a blank query to see the steps:

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WKi7ILyopVsjMS84pTUktVkjLzy9JSszJ0VEoSc3LyyzWSUpMyc3MK8nPU4rVIUJ5RmJeCkhAKTYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Col1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Col1", type text}}),

    #"Split Column by Character Transition" = Table.SplitColumn(#"Changed Type", "Col1", Splitter.SplitTextByCharacterTransition({","}, (c) => List.Contains({"a".."z", "A".."Z" }, c)), {"Col1.1", "Col1.2"})
in
    #"Split Column by Character Transition"

    You would have to create a new step with that code, best in the Advanced editor and change #"Changed Type" for the name of your previous step in the query and "Col1" for the name of the column with the data. 

    If you have share a pbix with your data (or some mock data with the same table structure we will be able to work it out

    thank @aib, I see that this works in your example but I am struggling to get it to work on my data. Specifically I am unsure how to apply this to my existing variables. I have no idea about M code.

     

    Is it a case of writing the following in the formula bar and changing the "Col1" names?

     

    = Table.SplitColumn(#"Changed Type", "Col1", Splitter.SplitTextByCharacterTransition({","}, (c) => List.Contains({"a".."z", "A".."Z" }, c)), {"Col1.1", "Col1.2"})

    Best,
